A Brooklyn judge has cut in on an auction house trying to sell off the glitzy dance floor used in the disco-era movie “Saturday Night Fever.”

Brooklyn Supreme Court Justice Ira Harkavy yesterday issued a temporary restraining order preventing the Beverly Hills-based “Profiles in America” from auctioning the famous floor used in the 1977 John Travolta flick.

Party promoter Vito Bruno claims he won the rights to the light-flashing floor for $6,000 in an auction on Feb. 15.

It was never delivered, and he is suing Spectrum – the now-defunct Brooklyn club where the film was shot – as well as its owner and the man who set up the auction.

A spokeswoman for the company running the new auction said it hasn’t yet gotten any official notice that the floor should be shelved.
